. rose diagrams . from Therion sql exports. have some teething problems


One is that the Therion sql export does not distinguish sufficiently survey
legs from splay shots.

(well, either Therion or the code used to manipulate the sql file)


Hence the rose diagram reflects a combination of survey legs and splay
shots, hence giving a somewhat meaningless (circular) result, especially
where electronic surveying with copious splay shots has been employed.

It works well where LRUD is used without splay shots however.
